Time dependence of optical absorption in np‐layered superlattice structures

摘要

Recent experimental data measuring channel conductance in np‐layered superlattice structures during optical excitation have been used in a phenomenological calculation to determine the optical absorption coefficient as a function of time. Additionally, internal fields and depletion widths as functions of time are calculated. With the appropriate data one may also determine these quantities as a function of irradiation intensity and energy. This type of information should prove valuable in electro‐optical device applications.
